Pulse nuts in a food processor until the pieces are somewhat uniform in size. Some larger chunks may remain.
Add the dates and cocoa powder and process until most of the mixture minced.
Add the strawberries and process until the mixture starts to come together in a mostly cohesive massive.
Pinch off chunks of the mixture and roll into balls.
Notes
Dates come in many sizes and types so what you use may dictate how many you need for this recipe. Medjool dates are larger and darker. Deglet Noor dates are smaller and lighter. You can use either but will need about 50% more Deglet Noor dates than Medjool.Most nuts will work well. I have experimented with almonds, walnuts, cashews, and pecans. Store the bars in an air-tighter container at room temperature for up to two weeks.
